Integral Cayley multigraphs over Abelian and Hamiltonian groups

Matt DeVos, Roi Krakovski, Bojan Mohar +1

It is shown that a Cayley multigraph over a group $G$ with generating multiset $S$ is integral (i.e., all of its eigenvalues are integers) if $S$ lies in the integral cone over the…

Spectrum of Cayley graphs on the symmetric group generated by transpositions

Roi Krakovski, Bojan Mohar

For an integer $n \geq 2$ , let $X_{n}$ be the Cayley graph on the symmetric group $S_{n}$ generated by the set of transpositions $(12), (13), ..., (1 n)$ . It is shown that the spectrum…
